Although your Multiplexing system is operat-
ing properly it may not be completely effec-
tive. People may not hear or heed your
messages. You must recognize this fact and
ensure that your messages achieve their
intended effect through proper test and
training sequences suitable for your specific
application(s).
4-1. After completion of installation be sure to test
the system to verify that each unit operates satisfac-
torily.
4-2. Provide a copy of these instructions for the
Safety Engineer(s), System Operators(s) and Mainte-
nance personal.

6 KEY TO RECORD A MESSAGE”.
Press the 9 key, the message “ENTER NEW
PASSWORD” will inform the caller to enter a new
password. The same new password must be entered
twice. The caller will hear the message “PASSWORD
CHANGED” then the message “GOODBYE” and the
system hangs up the phone line.
The password can be returned to the default
“12345678” by opening the cover of the Router and
